A FF program and a codeshare/alliance with major international carrier is all that's missing to catapult B6 straight to #1.

Looking at the all the int'l flights arriving at JFK, there is great potential to link up with someone like Virgin Atlantic for example, even though the JFK scene is pretty heavily O&D rather than transfer pax.

jetBlue is working on getting a frequent flyer program ready. Remember, one of the things that makes low-fare airlines low-fare is keeping costs down (duh; though jetBlue still manages to equip thier planes "fully loaded"; including rafts and over-water beacons that allow FLL-JFK to be flown in 2.05h instead of the 2.50h it takes a DL 737 without rafts and over-water beacons; though in the end, that simple investments makes everything more efficient; okay back to the subject). A FF flyer program does not do this, so expect a fairly simple program.
